Article Abstract
Basaltic glass was prepared via the solid-state melt method, using Ce to simulate tetravalent actinides. The structure, thermal stability and leaching characteristics of basaltic glass with different contents of CeO were investigated. The XRD/SEM-EDX/Raman results showed that the simulated waste loading of CeO in basaltic glass reached ~ 18 wt%, and CeO crystals precipitated when the CeO content reached 20 wt%. XPS analysis revealed that approximately half of the Ce ions in the basaltic glass doped with CeO were reduced to Ce ions. The DSC results showed that the thermal stability increased with increasing CeO content. The ASTM product consistency test (PCT) results indicated that all the samples had good leaching resistance. Among them, the standard mass loss of Ce was the greatest after 28 days: The NL was 2 orders of magnitude lower than those of the other elements.

While under-ice submarine hydrothermal systems provide critical insights into extremophile adaptations, the ecological impacts of explosive volcanism on these ecosystems remain poorly constrained. We successfully detected evidence of hydrothermal activities and explosive volcanism at 85° E, the eastern volcanic zone, ultra-slow spreading Gakkel Ridge. Hydrothermal plume, surface sediments, and volcanic glass samples were systematically collected to investigate the diversity of microbial communities.

Drilling-induced damage in fiber-reinforced polymer composite materials was measured excavating four laminates, basalt (B), glass (G) and their two sandwich type hybrids (BGB, GBG), with 6 mm twist drills at 1520 revolutions per minute and 0.10 mm rev under dry running with an uncoated high-speed steel (HSS-R), grind-coated high-speed steel (HSS-G) or physical vapor deposition-coated (high-speed steel coated with Titanium Nitride (TiN) and Titanium Aluminum Nitride (TiAlN)) drill bits. The hybrid sheets were deliberately incorporated to clarify how alternating basalt-glass architectures redistribute interlaminar stresses during drilling, while the hard, low-friction TiN and TiAlN ceramic coatings enhance cutting performance by forming a heat-resistant tribological barrier that lowers tool-workpiece adhesion, reduces interface temperature, and thereby suppresses thrust-induced delamination.

The construction industry is exploring alternatives to traditional steel reinforcement in concrete due to steel's corrosion vulnerability. Glass Fiber Reinforced Polymer (GFRP) and Basalt Fiber Reinforced Polymer (BFRP), known for their high tensile strength and corrosion resistance, are viable options. This study evaluates the flexural performance of concrete beams reinforced with GFRP, BFRP, and hybrid systems combining these materials with steel, following ACI 440.

This study focuses on the influence of prolonged ultraviolet (UV) irradiation on the mechanical properties and surface microstructure of glass fiber-reinforced plastics (GFRPs) and basalt fiber-reinforced plastics (BFRPs), which are widely used in construction and transport infrastructure. The relevance of the research lies in the need to improve the reliability of composite materials under extended exposure to harsh climatic conditions. Experimental tests were conducted in a laboratory UV chamber over 2000 h, simulating accelerated weathering.
